Compatibility

VShard 0.1.25 is fully compatible with the previous VShard versions.

Functionality added or changed

• Added support of master='auto' on the storage side. It makes the storages dynamically track who of them is the master (no election, only tracking and automatic role switch) (gh-429).
• Introduced rebalancer flag for replicas and replicasets to be able to choose manually who of them should run the rebalancer service (gh-432).
• Introduced rebalancer_mode which can be used to enforce manual or automatic rebalancer assignment, or turn the rebalancer off completely (gh-432).
• Config can be used with instance and replicaset names instead of UUIDs - for that there is a new option identification_mode. When specified as uuid_as_key (default) the behaviour is like in 0.1.24 and before. The value name_as_key unlocks the new behaviour (gh-426).

Bugs fixed

• Fixed a bug when bucket recovery and GC could sometimes do a bit more work than needed in case manual vshard.storage.bucket_send() was used (gh-434).
• Fixed a bug when vshard.storage.send() could false-positively fail in the end or the beginning of its work (gh-433).
• Fixed a bug that the router couldn't call storage functions implemented in C or having their Lua body stored in _func (gh-436).
